It is an indispensable steel variety in the process of industrialization and development. The development course of the world steel industry shows that the level of production and material of wide-thick plate is also an important symbol of the level of the national steel industry.The design is the annual output of 2.12 million tons of heavy plate production workshop, the typical product for the GB3531-09MnNiDR, on behalf of the product specifications for 13x 4000x9000mm. In the design process of the whole workshop, the production technology and development, the gap between domestic and international production technology and the new technology of core rolling are introduced. In this design, the rolling need to longitudinal rolling, but also need to transfer steel in the rolling gap. Rolling equipment includes: two walking beam heating furnace, tumbling Machine, high pressure water descaling unit, a four-high reversing mill, PC rolling mill, and various ancillary equipment. In the design, based on a set of annual output, combined with the market prospect of the product, the product scheme was designed with reasonable design method and technical rules. Taking typical products as an example, the process flow and rolling schedule are established. The rolling system includes: systems of pressure, velocity and temperature system; rolling force calculation are carried out and the strength of the roller and the load of the motor are checked. In the design, the working time of the year is reasonable, so that the production capacity of the workshop is maximized. According to the annual working time and rolling mill production capacity, the annual production capacity is calculated, and the various economic and technical indicators and measures for environmental protection are put forward. Through strict and careful calculation and verification, finally come to a scientific and rational design of the generous plate workshop. Workshop design program contains a shop floor plan, and finally with a foreign language information and translation. The design features of the workshop include: process leading, advanced equipment, Products high strength, good mechanical properties, and greatly optimize the protection of environmental protection. Generally speaking, achieve high yield and low consumption.Key words: Wide-thick plate; The design of workshop; Rolling schedule; Low pressure container plate目录1 概述11.1 宽厚板的定义及用途11.2 宽厚板国内外发展状况11.2.1 国外宽厚板发展状况11.2.2 国外厚板轧机的发展21.2.3 轧制技术的发展现状41.2.4 我国宽厚板发展概况61.2.5 宽厚板生产的发展趋势72 产品大纲及技术要求92.1 产品大纲92.2 金属平衡表113 生产工艺流程及轧机的选择113.1 轧机的主要类型及布置形式113.1.1 现代宽厚板的轧机设备113.1.2 轧机的布置形式143.2 宽厚板的加热设备及高压水除鳞系统163.2.1 加热炉163.2.2 高压水除鳞系统183.3 矫直机193.3.1 概述193.3.2 宽厚板矫直机的类型193.4 冷床203.4.1 概述203.4.2 冷床的主要形式203.5 剪切设备213.5.1 概述213.5.2 宽厚板生产的剪切机类型213.6 热处理炉243.6.1 概述243.6.2 热处理炉的分类243.7 淬火机253.7.1 淬火处理253.7.2 宽厚板淬火机253.8 车间自动化装置263.9 四辊轧机电动APC和液压AGC263.10 在线检测措施及仪表273.10.1 在线检测的主要措施273.10.2 在线检测仪表273.11 计算机控制系统284 工艺布置方案、流程及制度294.1 工艺布置方案294.1.1 宽厚板生产的主要特点294.1.2 宽厚板工厂平面布置概略294.2 工艺流程314.3 工艺流程简述324.4 工艺制度334.4.1 板坯准备制度334.4.2 板坯加热制度344.5 轧制制度354.6 精整制度364.6.1 矫直364.6.2 冷却374.6.3 剪切374.6.4 检查打印374.6.5 钢板收集和堆垛374.6.6 热处理制度384.7 入库384.8 热处理及涂漆线（预留）385 轧机主要参数的确定和生产能力计算395.1 轧辊主要参数的确定395.1.1 轧辊材质及轧辊轴承的确定395.1.2 工作辊辊身长度的确定405.1.3 工作辊辊身直径的确定405.1.4 支撑辊辊身直径的确定405.1.5 支撑辊辊身长度的确定405.1.6 工作辊辊颈尺寸的确定405.1.7 支撑辊辊颈尺寸的确定415.2 轧机允许轧制力矩的确定415.3 轧制速度和主电机主要参数的确定425.3.1 轧制速度的确定425.3.2 主电机型式的选择425.3.3 主电机额定转速的确定425.3.4 主电机额定功率的确定435.4 压下规程设计445.4.1 宽厚板轧制各道次压下率445.4.2 代表钢种坯料成品规格455.4.3 代表钢种的计算过程455.4.4 各代表钢种的压下规程表475.5 轧机强度校核495.5.1 支撑辊强度校核515.5.2 工作辊强度的校核515.6 电机校核525.6.1 电机传动轧辊所需力矩的计算525.6.2 轧制力矩525.6.3 摩擦力矩
